Evaluation of Eyes and Vision
Ophthalmologists in Guatemala are doctors, physicians, or osteopaths, specialized in the care of vision and eyes, in addition to being licensed to practice their profession as surgeons.
This additional training allows ophthalmologists to treat and diagnose a wider range of diseases than opticians and optometrists. He also fits and prescribes contact lenses and glasses to correct vision problems. As physicians, ophthalmologists can sometimes detect health problems that are not directly related to the eyes and can refer these patients to the appropriate specialists for treatment.
Ophthalmology is a broad branch, 5 of the most common conditions treated by ophthalmologists in Guatemala are:
Nearsightedness (myopia) is a refractive error and affects distance vision. Refractive error occurs when the eye does not properly bend light. The images are not clear, because the light is not focused correctly. In nearsightedness, objects that are close to vision are seen clearly, but objects that are far away are blurred. Nearsightedness is a very common condition and is an eye focusing disorder, not an eye disease.
Hyperopia is a common vision disorder in which objects in the distance are clearly seen, but those that are close can be diffuse. The degree of hyperopia can affect focusing ability. Hyperopia usually occurs at birth and is usually inherited. Fortunately, this condition can be easily corrected with contact lenses or glasses. Another option is surgery.
Strabismus occurs when the eyes are not properly aligned and pointing in different directions. One eye can point to the nose, outward, upward, or downward, and the other eye can look forward. Misalignment may alternate between one eye and the other. Strabismus impairs vision because, to see properly, both eyes must point in the same direction.
Macular degeneration is an eye disorder that slowly destroys sharp, central vision, making it difficult to see fine details and perform activities such as driving or reading. It does not hurt, but it causes the death of the cells of the macular. There are two kinds: dry and wet. Dry macular degeneration occurs when light-sensitive cells of the macular are damaged and central vision is slowly lost. One of the first signs is the visualization of distorted straight lines.
Wet macular degeneration occurs when abnormal blood vessels enlarge under the macular. These new vessels usually leak fluid and blood. This damage to the macular happens quickly. One of the first signs is the blurred vision. This condition is more common in patients over 60, which is why it is often called age-related macular degeneration (AMD or AMD).
Retinal Detachment: The retina, which is a layer of tissue at the back of the eye that senses light and sends images to the brain. It provides the sharp, central vision needed for reading, driving, and seeing the smallest details. The detachment of the retina from its normal position due to a tear is called a retinal detachment. It can happen to people of all ages but is most common in people over 40 years of age. This problem affects more men than women and more whites than African Americans.
To provide a better quality of life to patients, there are several procedures to treat some diseases, 4 of the most common treatments and procedures performed by ophthalmologists in Guatemala are:
Intraocular lenses are clear artificial lenses, which are implanted in the eye in cataract surgery, to replace the natural cloudy lenses. Intraocular lenses perform the same function as the eye’s natural lens: they focus light entering the eye through the cornea and pupil onto the retina, which transmits images to the brain via the optic nerve.
Refractive surgery is a procedure to improve or correct vision. There are several surgical methods to accommodate the focusing ability of the eye by adapting the cornea (the round, transparent dome in the front area of the eye).
The most commonly practiced type of refractive surgery is LASIK (Laser-Assisted in Situ Keratomileusis). This technique permanently changes the structure of the cornea and is used to reduce the patient’s need for contact lenses or glasses, improving their vision.
Contact lenses are clear, thin plastic discs that are worn in the eye to improve vision. These lenses float on top of the tear film that covers the cornea. Like eyeglasses, contact lenses improve vision conditions caused by refractive errors.
A refractive error occurs when the eye fails to refract (focus or bend) light properly within the eye, projecting a blurred image.
Corneal transplantation is a surgical practice in which part of the cornea is replaced with corneal tissue from a donor.
This type of transplant can restore vision, improve pain, and renew the appearance of a diseased or damaged cornea. Almost all corneal transplants are successful. This does not mean that it does not carry a minimal risk of complications, such as rejection of the donor’s cornea.
With a corneal transplant, many conditions can be treated, such as a cornea that grows outwards, thinning of the cornea, corneal scars caused by an infection or injury, swelling of the cornea, opacity in the cornea, complications caused by previous eye surgery, among others.
